Hi all，

Centred on Hesperia, with Hellas at upper right and the bright edge artefact badly affected by Syrtis Major being on the limb.

The bright streak on the east of SM I think is just the normal bright patch, possibly exacerbated by the edge artefact.

Best regards, Clyde

Hi all，

An interesting morning session as I had extreme variations in seeing conditions.

After nice conditions for Saturn, I just managed to catch these single R, G and B's as the seeing dropped off a cliff. The rest of the RGB was terrible, and I was about to close everything down when I noticed a slight improvement as I captured the final attempts at IR.

I still have to process the Jupiter results, but it looked like the seeing may have recovered significantly towards sunrise.

Syrtis Major and Hellas dominate the view and it seems that there is significant brightening in the northern section of Hellas.

The Perseverance rover region looks reasonably clear.

Best regards, Clyde

I had improved conditions this morning with Syrtis Major and Hellas dominating the central longitudes of the planet, and Sinus Sabaeus extends to the centre right.

The region over Perseverance rover appears reasonably clear.

Hi all，

I only had a short session on Mars as my priority this morning was the Juno PJ42 flyby.

Unfortunately seeing was poor, with the shorter wavelengths badly affected.

Hellas, at upper left, shows as a bit bright. The Chryse region, where there may be some bright activity, reported by Antonio, had not rotated into view.

Hi all，

I had generally poor conditions this morning with a strong jetstream. I suspect that the faster framerate (200fps) on Mars was a significant factor in getting some reasonable results from the conditions.

Sinus Meridiani and Sinus Sabaeus extend across the centre of the planet. Hellas is just coming into view at upper left and Argyre still shows as a bit light at upper right. The SPC structure remains interesting.

Best regards, Clyde

I note that the De has just turned at 25 deg south, so assume this is our most southerly view of Mars.

Hi all，

The recent jet stream had eased up a bit this morning and it was a pleasant session as I also kept an eye on the lunar eclipse as it progressed in the west.

Sinus Meridiani is coming into view, with Indus quite prominent just below centre. Chryse is at lower right and M Erythraeum extending across much of the upper right hemisphere. Argyre is a bit light below the SPC.

Hi all，

Strong jet stream conditions this morning, and I ended up using only the single best captures. The RGB processing was particularly challenging with the large dark areas, low contrast, and bright Tharsis limb.

M Erythraeum again dominates the southern hemisphere. Argyre can be made out at the edge of the SPC, and Oxia Palus again shows a bit bright.

There is a perception of widespread atmospheric dustiness, but this could also be the poor conditions

Hi all，

Reasonable seeing for Mars despite some jetstream this morning.

Argyre is seen just below the SPC, with M Erythraeum extending across the upper left section of the planet. The Valles Marineris complex is central, with Aurorae Sinus. Chryse is at lower left. The R and RGB appear to show some interesting detail, with Eos possibly being detected. The atmosphere seems reasonably clear.

Hi all，

I had fairly average seeing this morning.

Valles Marineris and Aurorae Sinus are central. Solis Lacus is towards upper right.

Once again the RGB gives the impression of some level of dustiness in the atmosphere, particularly near the terminator. Features in M Erythraeum can still be seen extending towards the terminator, so if dust is there, it's my view that its not particularly concentrated.

Hi all，

I was up a bit later than normal as I was anticipating stronger jet stream conditions. But I found that conditions were good, and I scrambled to catch what I could of the bright morning planets before sunrise.

The view looks down on the Valles Marineris complex extending from the terminator to the centre with Solis Lacus nicely seen above centre. The terminator gives the impression (in RGB) of being dusty, but whether this is the case, or not, should become clearer in the next few days. Oh, and Mars has reached 6"!

Hi all，

Very poor conditions this morning and the G and B were unuseable. The IR was the best, but I did try to derotate a few poor R's. Solis Lacus is just above centre.

As always under these conditions I would be very wary of making any definitive comments, but hope that they may offer some comparison with better captures.

It appears to me that Araxes and Arcti Fretum are unusually prominent, to the west of Phasis. Also, Arsia Mons appears as a dark spot in the middle of a continuous line from Phoenicis Lacus to Nodus Gordii. These features are somewhat different from their usual appearance. 

Araxes, when prominent in the past, has also been referred to as "the Sirenum extension" as it crosses Daedalia, but it seems to me that the current view of Araxes as your image displays it is just a bit west of the extension seen in 2010-11 as I recall it.

Hi all，

A very brief session yesterday morning. M Sirenum is at upper right, and Solis Lacus at upper left.

Daedalia is between them, with Phasis extending below Aonis Sinus which is not very prominent. Claritas is quite bright.

Olympus Mons is approaching the limb at lower right. The Valles Marineris sytem extends from the terminator to the centre.

This hemisphere of the planet appears to remain free of any significant dust activity.

¤¤••••• Subject: Mars 6 May 0422UT RGB and IR. Southern Dust activity?

Received: 7 May 2022 at 01:35 JST

Hi all，

Seeing conditions were very poor this morning and I was tempted to abort. I did however continue, and used the best (very limited useable data) of what I captured.

Given the poor conditions, the face of the planet seems clear of any significant dust activity. I was however a bit intrigued by the SW limb (upper right), and the SPC, and am wondering if the dust activity that is reported to have emanated from Hellas may be extending along the edge of, and possibly onto, the SPC.

This off course also falls in the edge artefact region and better conditions would be required to confirm this.

Best regards, Clyde

Hi all，

Conditions were not as good as a few days ago.

Olympus Mons is towards the bottom (best seen in the IR) with Valles Marineris on the terminator at centre left. Solis Lacus is on the terminator at upper left.

This region still appears to be clear of any dust activity.

Hi all，

There is some talk of possible expanding dust activity in Hellas.

But it appears to be clear in this region, with Olympus Mons well seen at lower left and cloud remains over Arsia Mons. M Sirenum is at upper centre and there still appears to be some dust on/over the SPC.

Hi all，

I had some improved conditions this morning, with Mars centred on Amazonis.

Olympus Mons is nicely seen at lower left and there is cloud over the Arsia Mons region. Unfortunately, with the improved seeing and gibbous phase, the edge artefact is very unpleasant.
